Under Section 6(b), the Central Government shall remove a member who refuses to act or becomes incapable of acting, and this ground for removal, UNLIKE removal under clauses (a) [for the Section 4(e) disqualification] and (d), does NOT require:

Section 6(b) covers removal for refusal to act or incapacity to act - a largely self-evident, factual trigger - and unlike the specific provisos attached to clause (a) (removal for the Section 4(e) financial/other-interest disqualification) and clause (d) (removal for abuse of position), clause (b) carries NO express requirement of a reasonable opportunity of being heard before removal. This selective natural-justice safeguard (applicable only to clauses (a)-for-4(e) and (d), not uniformly to clause (b) or clause (c)-absence-from-meetings) reflects the legislature's judgment that refusal/incapacity to act is typically an objectively verifiable fact not requiring the same procedural protection as more subjective, opinion-based removal grounds like abuse of position or adverse financial interest.
